Abstract (en)
[origin: WO2022017675A1] The invention relates to a method for operating a spring-loaded drive (30) of a medium-voltage switchgear system (10), to a spring-loaded drive (30), and to a medium-voltage switchgear system (10) having a spring-loaded drive (30) of this type. The method according to the invention for operating a spring-loaded drive (30) of a medium-voltage switchgear system (10) has at least the following steps: - measuring a drive current of an electric auxiliary drive (31) for loading a drive spring (34) of the spring-loaded drive (30) of the medium-voltage switchgear system (10); - loading the drive spring (34) by means of the electric auxiliary drive (31); - creating an evaluation data set in accordance with the measured drive current; - comparing the evaluation data set with an expectation; and - outputting a maintenance signal in accordance with a result of the comparison.
